Frequently asked questions

It’s built for organizations that have up to 300 seats and use Microsoft 365 Business Premium.
  • Microsoft Defender Suite for Business Premium helps detect, prevent, and respond to phishing, ransomware, and identity attacks, while reducing the risk of unauthorized access or data breaches. Microsoft Defender Suite for Business Premium also provides clear visibility across devices, email, identities, IoT, and cloud apps—critical for teams managing security with limited resources.
  • No. Microsoft Defender Suite for Business Premium provides prebuilt policies, automated threat response, AI-driven recommendations, and clear dashboards—making it easy to deploy protection and manage alerts without deep security expertise. If you work with a partner, you’ll receive the visibility and controls needed to help secure and maintain your environment.
  • Microsoft Defender Suite for Business Premium helps enforce safe access and provides audit-ready reporting. It works across endpoints, identities, email, IoT, and cloud apps, reducing breach risk while helping teams meet internal and regulatory security requirements. Features such as just-in-time and just-enough access, along with automated investigation and response, support least-privilege and Zero Trust practices for stronger security.
  • Microsoft Defender Suite for Microsoft 365 Business Premium delivers the same product capabilities as Microsoft Defender Suite, offering enterprise-grade security without enterprise complexity to protect devices, identities, cloud apps, IoT, and data with:
    • Microsoft Entra ID P2
    • Microsoft Defender XDR
    • Microsoft Defender for Endpoint P2
    • Microsoft Defender for Office 365 P2
    • Microsoft Defender for Identity
    • Microsoft Defender for Cloud Apps
    • Microsoft Defender for IoT—EIoT
  • Microsoft Defender Suite for Business Premium upgrades your built-in protection to enterprise-grade security. Business Premium includes Defender for Business, Entra ID P1, and Intune. Microsoft Defender Suite adds Microsoft Defender XDR, Defender for Endpoint P2, Defender for Office 365 P2, Defender for Identity, Defender for Cloud Apps, Defender for IoT, and Entra ID P2, unifying threat detection and response across identities, endpoints, email, and cloud apps for up to 300 users.
  • Yes. Microsoft 365 Business Premium includes Microsoft Defender for Business for everyday antivirus and endpoint protection. Microsoft Defender Suite for Business Premium goes further with extended detection and response (XDR): it correlates signals across endpoints, email, identities, and cloud apps, adds identity threat protection and automated investigation, and helps stop AI-driven phishing and malware that slip past basic antivirus.
  • Microsoft Defender XDR is an extended detection and response (XDR) platform, previously called Microsoft 365 Defender. It brings alerts from endpoints, email, identities, and cloud apps into one view, correlates them into single incidents, and can automatically investigate and contain threats. In Microsoft 365 Business Premium, you get Defender XDR by adding Microsoft Defender Suite.
  • Defender for Business, included in Business Premium, delivers endpoint protection and EDR for your devices. Microsoft Defender Suite adds Defender for Endpoint P2 plus protection for email, identities, and cloud apps, and ties it together with Defender XDR for cross-signal detection, threat hunting, and automated response, closer to the security in Microsoft 365 E5 at an affordable price.
  • ITDR protects the accounts and credentials attackers target first. Microsoft Defender Suite provides it through Microsoft Defender for Identity and Microsoft Entra ID P2, detecting suspicious sign-ins, credential theft, and lateral movement, and applying risk-based access to contain compromised users. Multifactor authentication alone blocks over 99% of password-based attacks9 .
  • Most attacks on small businesses start in email so endpoint protection alone leaves a gap. Microsoft Defender Suite for Microsoft 365 Business Premium covers both: Defender for Office 365 P2 guards email, Teams, and collaboration against phishing, malware, and malicious links, while Defender for Endpoint P2 protects devices. Defender XDR connects the two, so an email-borne threat that reaches a laptop is caught as one incident.
  • A growing business needs enough security to cover the surfaces attackers actually use: identities, endpoints, email, and cloud apps. Smaller teams face the same phishing, ransomware, and identity attacks as large enterprises, often with fewer people to manage them. An all-in-one solution like Microsoft Defender Suite for Microsoft 365 Business Premium gives right-sized, enterprise-grade protection in one place, so you get broad coverage without stitching together point tools.
